"What, you guys don't have robots?"
- Related "rich elite man" after replacing all of his human workers for robots
In all seriousness tho -- robots require energy (and lots of it) in order to work efficiently. While "any ordinary human" has to pay for his own expenses. Which means, robots will be (best case scenario) a "gimmick" for a selected few and no way a popular thing, in a way that will make all humans irrelevant for ANY kind of job.
tl;dr: It's okay, robots won't take over the world.
